Oh god.
I would get a heart attack.
I just bought 60 boxes of Litebeam AC and 10 boxes of Rocket AC PRISM with 60 degree AC sector.

Re: Huge signal drop from PBE-M5-400 to PBE-5AC-400

HI Guys --

 

Still working on this.  It's difficult to pinpoint and does not appear to consistently behave.  From our findings so far, things look OK at higher signal links, but the 5AC receivers in some cases will not perform as well as M5 in low signals (high -70s and below to -80's).  

 

The good news is from our tests, Rocket 5AC Prism has been superior to Rocket M5 in all cases.

 

5AC is our highest priority and even I am back in the lab working on it.  Please hang in there; we will improve!

Good to hear Robert!
So, basically the next beta version will be improved version for 5AC CPE ?

Hi guys! I'm new here! And sorry for my English!

UBNT, the solution of the problem will appear software or to change the dish?

Acquired LiteBeam 5AC in the hope of a significant improvement of the signal in contrast to the Loco M5 in the end received the same signal levels. Firmware WA.v8.0-beta14.31151.160610.1509.

So has UBNT made any progress on eliminating bad focal point (a physical problem requiring replacement) as the issue behind the weak rx signal on the powerbeam ac 400 radio?  Seems like that could be the problem...

 

The signal difference going from a powerbeam m5 400 to an ac 400 is just too large to ignore.

Guys -- We are close to zeroing in on issue

Over a month, have any news?  I don't see this issue in one area, but we're dealing with signals of -50db and better.  In another area we're dealing with a number of marginal clients, and moving from AirGrids to higher gain PB's has not given us the few dB of boost we expect.  Would be good to know what the plan is on your end and have a timeline.

Re: Huge signal drop from PBE-M5-400 to PBE-5AC-400

Not sure if this is related, but I've been swapping NBE-5AC-19s that are ~2mi out from my tower with LBE-5AC-23s, and the signal strengths aren't any better than the nanobeams... When 3dBi of gain doubles the signal strength, and the litebeams have 4dBi more gain than the nanobeams, I would have expected litebeam signals to be at least 3 or 4 dBi better than the nanobeams. Kind of odd. I swapped them to get better signal strengths and nothing has changed. Would that issue be related to what we're seeing here?

 

I upgraded one of the litebeams from v8b6 to v8b14 because in one of the beta releases before 14, there was a TX power issue fixed for WA boards, and that upgrade didn't help. I'm assuming that my issue is related to this thread. Any updates would be awesome! Smiley Happy

Sorry we don't have better news, but we are still looking for a solution for receiver performance issue

 

PBE-5AC-500 and PBE-5AC-620 look OK from our tests as well as NanoBeam 5AC

 

We have isolated issue to LBE-5AC, PBE-5AC-300/400.  In our outdoor link tests we have confirmed that in some cases, signal strenghth can be as much as 6dB lower than expected.

 

We continue to work towards a solution and will notify as soon as we have something

 

For longer distance links where signal strength is critical, we recommend using PBE-5AC-500

Re: Huge signal drop from PBE-M5-400 to PBE-5AC-400

Has this delayed production of the WA based radios until the issue is resolved? It just seems like supply is starting to dry up for those products.

Re: Huge signal drop from PBE-M5-400 to PBE-5AC-400

Yes, we are holding shipments for PBE 5AC 300/400 in case we cannot resolve with firmware fix.  If it turns out we cannot, we of course offer free upgrade to improved version

 

They are still OK otherwise in cases where there is sufficient signal strenghth.

 

For longer links, please use PBE-5AC-500  (or 620) until we can resolve 300/400 issue

Please make this #1 priority.. This has been going on way too long...

 

We've been deploying a lot of AC gear and its going well for the most part besides a few hiccups and some lower signals, but if 300/400s are not going to be shipping until you figure this out, I'll be forced to try another vendors flavor.. I don't need 500s at an added expense, I need working 300s and 400s, asap.

The LBE 23's are definitely stronger than the NBE19's. But require more careful aiming to acheive the improvement.

I've done a lot of comparison testing of the various AC products at various distance. 

At 2 miles, I start using PBE 500 AC's.   It never hurts to use more dish.  Might come in handy if there's increases in noise later.   I always try to over engineer my AC links and using PBE 500's is a big part of that.

@ClaudeSS you say you switch to 500's at 2 miles.  What do your usable miles/rssi numbers look like?  Say out to 3.5 miles?  I just found this thread while researching after switching a 2.1 mile LBE-5AC-23 link to UNII-1 and getting less than stellar results.

 

Don't let me derail the thread...

here's that other thread

Can you clarify if that is also true for the litebeams?

Re: Huge signal drop from PBE-M5-400 to PBE-5AC-400

@UBNT-Robert

 

Would a better "Fix" on this to be to eliminate the WA board in the PBE-5AC-300's and 400's and put in the XC boards, like the 500 dish uses?   (In the M series there was an upgrade from XM boards to XW boards, and they worked better)

 

Understand that the XC CPU board is a little more expensive, but I am sure we would all be willing to pay a little more if those dishes (which are a mainstay of our installs) worked better !
